Natural Cures for Diaper Rash

Hi, My husband's grandmother was changing my daughter's diaper yrs ago and she had at that time a severe diaper rash. Told her how I have tried many things but it seem to be getting a lot worse. She took some white flour and browned it up slowly in a pan and told me to sprinkle in on her bottom every time I changed her diaper and by morning it was near gone. I was shocked. Have used this many time for my grandchildren and it works like a charm. Hope someone can find this useful.
